锁定随机数组，以便可以通过其他方法对其进行处理而不会被随机化

Question

我正在用Java做二十一点游戏，做了一个创建纸牌的方法，然后是一个洗牌的方法。我还需要纸牌的数组列表以及其他功能，例如绘制纸牌的方法，但是每次我调用该方法时，它都会打乱新牌组。我想避免这种情况，但是我不知道如何...

这些方法定义并洗牌：

public static String[] kortlek() {

    String suit[] = { "S", "D", "C", "H" };
    String rank[] = { "2", "3", "4", "5", "6", "7", "8", "9", "10", "J",
            "Q", "K", "A" };
    String[] deck = new String[52];
    String[] shuffledDeck = new String[deck.length];
    int i = 0;

    for (i = 0; i < deck.length; i++) {
        deck[i] = rank[i % 13] + suit[i / 13];

    } // End of for loop

    deck = shuffledDeck(deck); 

    return deck;
}

public static String[] shuffledDeck(String [] shuffledDeck) {


    for (int i = 0; i < shuffledDeck.length; i++) {
        int index = (int) (Math.random() * shuffledDeck.length);

        String temp = shuffledDeck[i];
        shuffledDeck[i] = shuffledDeck[index];
        shuffledDeck[index] = temp;

    } // End of loop

    for (int i = 0; i < shuffledDeck.length; i++) {
        System.out.println(shuffledDeck[i]);
    }
    return shuffledDeck;
}

这个带有按钮actionListener方法的方法会抓一张牌：

public static String drawCard(int wichCard) {

    String[] deck = kortlek();

    String drawnCard = deck[0 + wichCard];
    System.out.println("The drawn card is: " + drawnCard);

    return drawnCard; 
}

actionListener：

if (event.getSource() == drawCard) {            

    counter++;
    String drawnCard = cardDeck.drawCard(counter);
    player.setText("The drawn card is: " + drawnCard);  
}

输出将是：

first draw:
1  2  3  4  5
drawn card = 1

2nd draw:
5  3  2  1  4
drawn card = 3

3rd draw:
5  2  4  1  3
drawn card = 4

我希望每次抽卡时，列表都不会随机化。怎么样？

谢谢！
